Brazing ZrB2 ultra‐high‐temperature ceramics to Zr metals for hypersonic thermal protection systems

International Journal of Applied Ceramic Technology, EarlyView.
Abstract Porous and dense zirconium diboride (ZrB2) materials are promising ultra‐high‐temperature ceramics (UHTCs) for transpiration cooling in hypersonic applications, providing an effective means to reduce component temperatures and mitigate oxidation effects. While porous ZrB2 enables coolant flow, dense ZrB2 offers structural integrity.

Insights on the volcanic and impact histories of the lunar nearside from the petrology, geochemistry, and geochronology of the Calcalong Creek lunar regolith breccia meteorite

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 392-421, March 2025.
Abstract The Calcalong Creek lunar meteorite is a regolith breccia with a lithologically diverse array of clasts set in a glassy, highly vesicular matrix. Here, we present a comprehensive new analysis of the meteorite. Comparisons to remote sensing data, lunar sample lithologies, and lunar sample ages indicate that it was likely sourced from regolith ...
